Systematized risk assessment and management in juveniles is still in its infancy, and the bulk of the validation literature focuses on males as they account for a significant proportion of crime. In recent years there has been growing recognition that female arrest rates and convictions are steadily increasing and that there is a need to ensure that risk assessment tools that have been validated with males are appropriate for females, who may have different criminal trajectories. The applicability of violence risk assessment tools for ethnically diverse populations has not been extensively examined, but the limited literature suggests that there may be differences in scores for risk and protective factors across ethnic groups. To address this subject, a review of the literature on the predictive validity of current juvenile risk assessment tools was performed. This summary produced equivocal findings and a requirement for further investigation comprising cohorts with greater diversity.
